Short answer: the KEF Muo gen2 for balance, and it is the cheaper of the two. KEF seems to have fixed the rolled-off treble and overall balance, though the Muo still lacks deeper bass. The Bose Soundlink Revolve+ II keeps its true 360 character wherever you stand, but pairs overly boosted bass with a warm overall sound.
What the Bose Soundlink Revolve+ II gets right: True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. Set against that: Overly boosted bass, warm sounding.
On the KEF Muo gen2 side: KEF seemed to have fixed the rolled off treble and overall balance. Set against that: Lacking deeper bass.
Buy the Bose Soundlink Revolve+ II if sound quality is the priority over the price, or the KEF Muo gen2 if the price is the priority over sound quality.

KEF Muo gen2: $249.99 Amazon eBay
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
